Hello, and welcome to Peak Efficiency.
Total Motors in the database:
Motors added in the last week:
User trials added in the last week:
There have been a lot of changes. For now, logging in is disabled while these changes
are being tested. You can still use most everything on the site, you just cant enter
new motor data for other users to see. Sorry for any trouble.
See the change log for more.
This website exists because I've found it overwhelming to track and compare brushless
motors, and also because I've been looking for a good project to learn SQL and ASP.NET.
Feel free to have a look around. I'd be pleased to hear any comments or feedback
on the site. Yes, it's a bit rough around the edges. But hopefully with time we can sand
those rough edges down.

Looking for a Motor?
If you are searching for a motor, click on "Search for a Motor"
on the left side of the window. This will let you search the entire database based
upon parameters that you can specify. You don't need to be logged in to use this
feature. Note that
most of the database is currently in-runner motors, and I don't (yet) have a way to specify gearing. But I'll add that in the coming months. In the meantime, I hope
to see a ton of outrunner data get added to the database.
Want to Graph a Motor You've Tested?
If you already know the Kv, Io and Rm constants for your motor then you can click
on "Graph a Motor" in the navigation bar to the left.
If you don't know the parameters for your motor, then you can enter the voltage,
current and RPM's
for two runs, along with the no-load current, and in return you'll
get graph of your motor's performance
that you can easily share with others using a link. Additionally, you'll be able
to clearly see which propellers will work best with your motor. You don't need to
be logged into use this feature.
To graph a motor's performance based upon this test data, click on "Find K, I & R"
in the navigation bar. By entering the no-load current, and the voltage, current
and RPMs of two load points you can calculate Kv, Io and Rm and then graphically
look at how different props will work on your motor.
Want to Add a Motor to the Database?
Once you've graphed your motor and you are confident in the data, you can add it to the
database for others to see and search. To help keep the quality of data high, you
need to be logged in to submit data. Logging in requires an account, which is free
To add a new motor to the database, or to add additional data on a motor that is
already in the database, click on "Add a Motor" in the navigation bar to the left.
